This week we discuss the story of how a dude held an entire town hostage for several hours with a literal home made tank destroying the property of anyone who he felt had done him wrong.. On June 4th 2004 Marvin Heemyer had finally had enough. He strapped into his home made tank. A heavily modified Komatsu D355 bulldozer, he plowed through the town of Granby Colorado while everyone simply stood by and watched in horror as he plowed through town hall and other buildings after a years long land/permit dispute with the town.
